Fig. 1 is the structural representation of the carbon fiber wire intermediate of a specific embodiment of the present invention.
To be carbon fiber wire intermediate shown in Figure 1 be bonded in structural representation on the heat-resisting main shaft by adhesive phase to Fig. 2.
The specific embodiment
In order more clearly to understand technology contents of the present invention, describe in detail especially exemplified by following examples.
See also Fig. 1-shown in Figure 2, the method that carbon fiber wire of the present invention is made carbon-to-carbon composition heating wire for the basis may further comprise the steps:
